GPT-Neo and GPT-J*
GPT-Neo and GPT-J are both open-source language models developed by EleutherAI. They are designed to provide capabilities similar to the GPT-3 model developed by OpenAI, but are freely available for anyone to use and modify.
### GPT-Neo
- **Release**: GPT-Neo was released in March 2021.
- **Architecture**: It is based on the transformer architecture and is designed to mimic the performance of GPT-3.
- **Models**: Different sizes were released, including 1.3 billion parameters and 2.7 billion parameters models.
- **Purpose**: It serves as an alternative for researchers and developers who want to use large language models without the restrictions or costs associated with proprietary models.
### GPT-J
- **Release**: GPT-J was released in April 2021 and represents a more advanced iteration compared to GPT-Neo.
- **Architecture**: GPT-J is a 6 billion parameter model and is trained to deliver better performance and capabilities.
- **Improvements**: It incorporates various improvements in training techniques and model architecture to enhance its performance on a range of NLP tasks.
- **Applications**: GPT-J is used in various applications, from conversational agents to text generation, summarization, and more.
Both models are part of EleutherAI's mission to democratize AI and make powerful tools accessible to a wider audience. They can be used for a variety of applications in natural language processing, and their architectures are similar to that of the well-known GPT models, making them suitable for many tasks that involve understanding and generating human language.
